Hello.
I am trying to verify the port of the v2 drivers by running an iguana lcd example.
I know how outdated is iguana from okl4 3's perspective, but I still want to see this port run.
This example begins my iguana example for gumstix (armv5) but fails to reach the example begin stage for my armv6 platform (macro ARCH_VER == 6):
--------- output using DEBUG_TRACE=5 in my platform -------------------
GRANT INTERRUPT (tid: 44, irq: 41)
bounce interrupt failed
41
iguana/server/src/bootinfo.c:1323 grant_interrupt: Record 427: Cannot register interrupt.
--- KD# User: PANIC: Bootinfo did not initialise correctly ---
This happens for the first GRANT INTERRUPT process.
As I see the bootinfo source tries to revoke the interrupt from it's implicit space (iguana) and then tries to grant the interrupt to the vserver space (vtimer for v2 timer driver,
vserial for v2 serial driver). This is done in two steps: calling soc_security_control_interrupt().
I see no obvious weaver.xml syntax cap differences between the two platforms involving this first interrupt.
I'm not sure if in order to grant initially the v2 driver's timer interrupt to iguana I need to look for the cause in the build script or in the iguana server initialization C code.
I would appreciate ideas from anybody who had this kind of problem before.
Thank you,
Gabi Voiculescu
